Researchers analyzed nearly half a million ransomware incidents between July and October. They found incidents of ransomware in 200 countries; 26 percent were in the United States.
“The results of our research shows that cybercriminal gangs have already saturated both the rural and urban U.S. populace with ransomware, yet they are constantly improving their tactics, execution and business model to evade detection by current solutions,” said Adam Kujawa, head of Malware Intelligence at Malwarebytes.
Las Vegas topped the list of U.S. cities with the most ransomware attacks. It was followed by Memphis, Stockton, Detroit, Toledo, Cleveland, Columbus, Buffalo, San Antonio and Fort Wayne, Indiana.
Ransomware is a type of malicious software that blocks access to your data until ransom is paid.
The three most common types of a ransomware detected were Cerber, Locky and CryptoWall. Last fall, researchers detected a surge in Locky incidents that made Locky the predominant ransomware family throughout the United States and in all the top U.S. cities.
Locky was released in February 2016 and has risen to become one of the most prolific ransomware attacks of the year.
